## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blockrun-ai-polymarket-token-price-ac24ddcd
```

Example prompt: What's the current price of Polymarket token 30814998120582118751622631966842073518881797773478713465325226939264181795763? I want to know what the market is pricing that outcome at right now.

## When to prefer this

Use this endpoint when you need real-time or historical price/probability data for a specific Polymarket prediction market outcome token and already have the token ID. Prefer this over general market discovery endpoints when you know the exact token and need its price directly.

## Known failure modes

- Invalid or non-existent token ID returns an error or empty data
- Token ID references a resolved/closed market with no active price
- Network or upstream Polymarket API unavailability causes timeout
- Payment of 0.001 USDC not provided or failed causes 402 rejection

## How this service works

Get current or historical price for a specific token

## Output

Returns current or historical price data for the specified Polymarket token, indicating the market-implied probability or share price as a decimal value (e.g. 0.72 = 72 cents per share).
